wmnow GUARD.

Application. filed March 30, 1928.

My invention relates to improvements in window guards.

My improved window guard is intended for use in connection with windowframes wherein a window sash is movable either in the frame, or to andfrom the frame so as to leave an opening. I am aware of the fact thatguards for such openings have heretofore been designed and that variousmeans for concealing the guard when the window is closed have beendisclosed.

The object, however, of my invention is to provide a window guard whichis entirely removable from a window frame and sash and at the same timeprovide a case for the members forming the guard in such a location asto protect the device from ice and the elements.

Another object of my invention is to so dispose a set of telescopic rodsand tubes within a housing for service as a window guard as to makepossible their telescopic extension to guard the entire window opening.

In the drawings:

Figure 1 is a front view of a two light sliding window structureprovided with my improved window guard.

Figure 2 is a similar view of the same window showing the sash closed inthe frame and showing the case cut away to disclose the guard incollapsed position.

Figure 3 is a section on line 33 of F igure 1.

Figure 4 is a detail front view of the method of attaching the case tothe sash.

Figure 5 is a section on line 55 of Figure 1.

Figure 6 is a section on line 66 of Figure 1.

Figure 7 is a detail of the member.

Figure 8 is a detail of the lateral guard member.

Figure 9 is a detail of a cross guard member.

Like parts are identified by the same refcentral guard erence charactersthroughout the several viewsrm I have here disclosed my deviceincorporated in a window structure wherein the window frame 10 providesa guideway 11 for a sliding sash element 12, stops 13 and 14 on eitherside of the window frame be Serial No. 265,915.

slides upwardly or downwardly. It will be obvious as I complete mydescription of my improved guard that it may be likewise at tached tocasement windows or other openable windows wherever there is an openingbetween sash and frame to be guarded.

It is of course well known that when a window such as that disclosed inthe drawings is tightly closed the lower rail 15 will rest partiallybelow the upper edge of the window sill 16 so as to make a water-tightlap joint therebetween. I, therefore, provide a construction which willbe adapted for installation adjacent the lower rail of the window sashand supported by the sill in the following manner.

My entire guard device is mounted upon a bed plate 17 and com rises as amajor part of its frame-work a ousing on case 10 superimposed upon thebed plate, and adapted to house the guard members hereinafter described,and since, as described above, it is of-importanee that the generalstructure of my device be easily removable from the window, I haveprovided for a telescopic structure in my bed plate as indicated at 18.It will likewise be noted that the outer ends 19 of the bed plate aremuch thinner than the central portion and it is by this means that Ienable the bed plate to be placed on any window sill and forcedoutwardly with light taps of a hammer upon the edges exposed adjacentthe telescopic joint 18, with the result that the thinned ends 19 willbe forced under the stop 13 with which all such windows are equipped.Small prongs 21 in the ends of the bed plate willbe forced into the woodof the frame 10 to prevent the bed plate from moving inwardly oroutwardly .of the window frame.

The housing aforesaid in essentially an invertedbox for which the bedplate forms a bottom and it is between these two members that thevarious elements of the guard form the only connection, each extensibleunit of the guard bein connected at its respective ends to the Eed plateand the housing.

The various extensible uard units may be classified for purposes 0%description into central, lateral and cross guards and it will beobvious in the light of the following dis closure that any number ofadditional guard fill embers could be supplied when a large tvindowis tobe equipped, the various types of guard members being adapted for use invarious combinations to meet all requirements.

The lateral members 22, since they have little space in which toretract, are made, as indicated in a plurality of parts, each beingreceivable into its mate so as to telescope into a fairly small space,the end parts being provided with pivot elements to receive brackets 23and 24c upon the bed plate and within the housing respectively. Thedimensions of the guard members 22 when contracted are determined by thehorizontal distance between their respective top and bottom pivotalpoints, between which these members must be received when the guard iscollapsed. The location of the pivot points in turn, is so chosen thatthe guard member will effectively block the opening which would exist itonly the diagonal or cross guard bars were employed.

The cross members 25, as will be obvious from an examination of Figure1, are only extensible to a small proportionate degree and are thereforemade in only two parts telescopically joined together,this member beinglikewise equipped with pivot elements which receive the brackets 26 and27 as indicated in Figures 5,8 and 9.

The central member 28 of the guard elements is of necessity morecomplicated than the others. It likewise extends between the case andbed plate, to which it is pivoted on brackets 29 and 30 similar to thebrackets 26 and 27, but in addition to the telescopic joint 31, I haveprovided a double hinged joint 32 which can break in either direction soas to permit the central member to fold into its space beside thelateral and cross members in the case as shown in Figure 2 when theguard structure is not in use.

All of the guard members are pivotally connected to the bed plate andcase, the pivots for members of the several types be ing disposed indifferent vertical transverse planes.

I have described the general construction of my device in so far as itsguard elements are concerned. It now remains to consider the method ofattaching the housing to the rail 150i the sash, since'obviously meansor" attachment and detachment must be provided if the guard is to beoptionally used, ordispensed with in the window opening. Since it isnecessary that the meansof attachment of the case to the rail 15 beinaccessibleto childrens fingers, Ihave provided a lock which issubstantially concealed 1within the case and operable only with a rey.1::

Upon the rail 15 I have, secured two brackets 33 which have an-oilsetportion 34 apertured as indicated in Figure 2. The ofiset portion 34 isadapted, when the windew and case are in operative relation, to bereceivable in aperture 35 in the outer margin of the top of the case andthe aperture in the offset portion 34 of the bracket is so p0si tionedas to register with a spring lock plug 86 which moves longitudinally ofa bayonet socket 37 at either end of the case as indicated in Figure 5,the lock plug 36 being provided with a key aperture 88 which willreceive any small L-shaped key to retract the plug from the aperture inpart 34 of the bracket 33 and if twisted to one side the plug will belocked in released position and the window with the brackets 33 may beraised without carrying the case upward to unfold the guard. If theguard is desired the key can be used to turn the plug 36, release thespring 40 which will force the plug into the apertured bracket 33 andcause the case to respond to any change of position of the rail 15,thereby unfolding the elements of the guard to the extent desired.

It will thus be seen that my guard is never in such a position as toprevent complete closure of the window and the guard itself is alwaysprotected by the window when the window is closed. Likewise the V entireguard, with the exception of the brackets 83 which will ordinarily bepermanently secured to the window, may be removed bodily from the windowby unlocking the case from the brackets 33, and telescopically reducingthe length of the bed plate 17.

It will be noted that the various elements of my improved guard do notleave any area of the'window opening exposed for the passage of so largea body as a child and that any number of additional memberscorresponding to one or another of my three types of such members may beused to increase the efliciency of my device.
